This course stresses the fundamental electromagnetic compatibility principles involved in typical grounding and shielding problems. Understanding the objectives and techniques for grounding and shielding will reduce misconceptions and allow a more systematic approach to replace trial and error methods. For example, the course explains why a signal ground is not the same as a signal return.
Also, solutions for the numerous problems caused by wiring inductance are described and demonstrated. The course emphasizes the development of logical diagnostic techniques for identifying various types of noise problems. Often, the correct identification of the problem is more difficult than the solution. The course is at an introdury level; however, some knowledge of electronic circuits and system design is assumed. Several interference mechanisms and shielding techniques are demonstrated.
